To aZZ whom it may concern:

Be it known that I, INcEBRE'r NYBAKKEN,

.l'iuprovemei'lts in ()il Cans, of which the following is a specification.

This invention relates to improvements in oil cans, and comprehends a construction wherein the oil is positively forced from the can under all conditions, the invention embodying amongst other teaturega cylinder arranged within the can and having valve controlled communication, with the discharge spout, at points adjacent the upper and lower end of the cylinder, the oil gravitating within the r-ylinder at either of said points, depending upon the position in which the can is arranged, and forced'from said cy inder through the instrumentality of plungers which are arranged to recipro cate within the cylinder.

The nature and advantages of the invention will be better understood when thefollowing detailed description is read in connection with the accompanying drawings, the invention residing in the construction, combination, and arrangement of parts as claimed. a

In the drawings forming part of this aplication, like numerals of reference indicate similar parts in the several views, and wherein Figure 1 can constructed in accordance sent invention. 1

Figure 2 is a sectional view taken on line 22 of Figure 1. p

Figure 3 is a perspective view of the cylinder and its .asssociated parts removed from the can.

Figure 4 is a sectional view showing the arrangement of the plungers when the can is used in an inverted position.

Figure 5 is a sectional view of a modified construction.

Referring to the drawings in detail, 10 indicates the can pro-per, which may be of any well known construction, and provided with a handle 11. The can is open at its upper end, but normally closedby means of a cover 12, and this cover is secured to the can in any suitable manner, preferably by means of fastening elements 13. Projecting from the cover 12 is the discharge spout 14:, while depending from the cover is the cylinis a sectional view through the with the pre} is. of a lengthto be arranged within the can 10, but that aportion of this cylinder proj ects above this cover and arranged in juXta-' The end, but 1sv position to the discharge spout. cylinder is closed at its lower f der 1'5. It will be noted that the cylinder formed with an offset portion 18, in which operates a spring pressed valve 19, to 0011 tro-l communication between this ofl'set portion 18 and a tube 20, which projects from the offset portion 18 to convey the oil therefrom to the discharge spout 14. The can is provided with a filling opening normally closed by a plug 21, while depending from the filling opening is a screen 23 which prevents foreign i'natter from entering the can incident to the filling thereof, which foreign matter would obviously interfere with the operation oil? the ejector. Projecting from the cylinder at a point adjacent theuppen end thereof, is a laterally disposed tubular extension24t which establishes communication bet-ween the cylinder, and the discharge spout, while this communication is controlled by a spring pressed valve ar ranged to operate within the extension 24.. i The cylinder 1S provided at spaced points in its length with openings 26 and 2'7, the former being arranged adjacent the upper part of the cylinder,while the openings 27 are arranged adjacent the opposite end of the cylinder, and operating within the cylinder are spaced pistons 29 and 30, which control the admittance of oil through the said opening into the cylinder, and subsequently force the oil therefrom int-o adischarge spout 14. The pistons'are connected by a rod 31, and

surrounding this rod is a coiled spring 32, R

which has one end bearing against the upper piston 29, and its lower endbearing against a fixed pin 33, the spring operating to return the pistons to normal position after the latter have been depressed through the instrumentality of a piston rod 34 which is connected with the upper piston 29.

In practice, when the can used in the stated manner, the oil within the can enters the cylinder through the openings 27, and when the pistons as a unit are depressed,

this oil is forced by the lower piston 30 from the cylinder through the offset portion 18,

into the tube 20, unseating the valve 19 under such circumstances to establish communication between the cylinder and the tube 20. The oil is thus conveyed by the tube. 20 through the discharge spout 14.

When the can is used. in an inverted position, the oil, after the pistons as a unit have been depressed, enters the cylinder through the openings 26 above the piston 29, and incident to the return of the pistons to normal position under the influence of the spring 32, the oil is forced through the tubular extension 24, unseating the valve 25, into the discharge spout 14. It will be noted that the oil is not sucked into the cylinder, which is the cause of great annoyance to the oil cans depending upon suction, especially in cold weather, when the oil is cold and heavy, and the oil gravitates into the cylinder through the openings above mentioned, depending upon the particular position in which the can is used, so that the can will operate without failure under any and all conditions.

In Figure 5, I. have illustrated a modified construction, wherein 10 indicates the can, the latter varying, from the preferred form of the invention, in that the bottom 11 is arranged an appreciable distance above the lower edge of the can, and at one side of the center, this bottom is provided with a depending portion 12'. This latter mentioned portion receives the cylinder 15, and the intake 16 of this cylinder is arranged so that the can 10 is pumped entirely dry, or in other words, the entire contents of the can can be removed therefrom, The pump construction is the same as that described in connection. with the preferred form of the invention' lVhile it believed that from the foregoing description, the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described, and that such changes may be resorted to when desired as fall within the scope of what is claimed.

\Vhat I claim is I 1. In combination, an oil can, a discharge spout, a cylinder arranged within the can and having inlet openings at spaced points in its length, a tube establishing communication between the lower end of the cylinder and the discharge spout, a valve controlling said communication, spaced pistons operating within the cylinder, a second. valve controlling communication between the cylinder and the discharge spout adjacent the upper end of the cylinder, a rod connecting said pistons, and means for reciprocating said pistons within the cylinder as a unit, to force the oil from said cylinder to the discharge spout, said pistons controlling the admittance of oil to the cylinder through the adjacent opening.

2. In combination, an oil can having an opening in the top thereof, a cover for said opening, a discharge spout supported by the cover, a cylinder'depending from the cover, and having inlet openings at spaced points in its length, spaced pistons operating in said cylinder and arranged to control the admittance of oil into the cylinder to the adjacent openings, a rod connecting said pistons for simultaneous movement, means for reciprocating said pistons, a valve controlling communication between the cylinder and the discharge spout when the can is used in one position, a tube establishing communication between the lower end of the cylinder and the discharge spout. and a valve controlling said communication, and another valve controlling the admittance of oil through said discharge spout when the can is used in another position.

3. In combination, an oil can, a disclr rge spout therefor, a cylinder arranged .vithin the can, and having inlet openings at spaced points in its length, a tube arranged in parallelism with said cylinder and establishing communication between the lower end of the cylinder-and the discharge spout, a spring pressed valve controlling communication between the cylinder and said tube, a tubular extension projecting from the cylinder adjacent the upper end thereof, and communicating with the discharge spout, a spring pressed valve operating in said extension and controlling said communication, spaced pistons arranged in the cylinder and operable to draw oil into the cylinder and subsequently expel the oil therefrom, means whereby the pistons are moved in unison and resilient means for automatically returning the pistons from an active to a normal position.

In testimony whereof I affix my signature.

INGEBRET NYBAKKEN.
